Yes. My tools get worked on in my spare time, between paid work, which means that development might not be as fast as you like.
If you really want something fixed, you can jump it up my priority list by waving money at me.
Best thing to do is to contact me and we can talk about rates and so on.

Q: "Cool tools - May I include some of them on a commercial CD or on my website?"

Well, I do have a decent job - if you like my free tools and feel you owe me something,
buy one of my commercial tools, or use my Amazon links;
Amazon pays me a small provision if you make a purchase through this link - then I can buy some bread for my kids.
